+ *
+ *  If `Back' is YES, an attempt is made to use UCReverseTransChar() for
+ *  back translation which may be more efficient. (?)
+ *
+ *  If `stype' is st_URL, non-ASCII characters are URL-encoded instead.
+ *  The sequence of bytes being URL-encoded is the raw input character if
+ *  we couldn't translate it from `cs_in' (CJK etc.); otherwise it is the
+ *  UTF-8 representation if either `cs_to' requires this or if the
+ *  character's Unicode value is > 255, otherwise it should be the iso-8859-1
+ *  representation.
+ *  No general URL-encoding occurs for displayable ASCII characters and

+ *  This function is called from the SGML parser to look at comments
+ *  and see whether we should collect some info from them.  Currently
+ *  it only looks for comments with Message-Id and Subject info, in the
+ *  exact form generated by MHonArc for archived mailing list.  If found,
+ *  the info is stored in the document's HTParentAnchor.  It can later be
+ *  used for generating a mail response.
+ *
+ *  We are extra picky here because there isn't any official definition
+ *  for these kinds of comments - we might (and still can) misinterpret
+ *  arbitrary comments as something they aren't.
+ *
+ *  If something doesn't look right, for example invalid characters, the
+ *  strings are not stored.  Mail responses will use something else as
+ *  the subject, probably the document URL, and will not have an
+ *  In-Reply-To header.
+ *
+ *  All this is a hack - to do this the right way, mailing list archivers
+ *  would have to agree on some better mechanism to make this kind of info
+ *  from original mail headers available, for example using LINK.  - kw
